Former Deadwood star Timothy Olyphant talked Thursday about HBO’s long-gestating revival movie for the hit Western series and the challenges of getting the cast back together.

“It’s very hard to get people together for a barbecue that lasts an afternoon, let alone to get everyone together for a production that lasts a month or two,” Olyphant told radio host Rich Eisen in an interview Thursday.

HBO president Casey Bloys confirmed to Deadline at TCA in January that the premium cabler is looking at fall 2018 for production to start on the highly anticipated film.

Created by David Milch, Deadwood starred Ian McShane as merciless saloon owner Al Swearengen, along with Olyphant as Seth Bullock, Molly Parker as Alma Garet and Brad Dourif as Doc Cochran. The acclaimed series ran for three seasons from 2004-2006 before abruptly ending its run, and there have been calls for and talk of a revival ever since.

“Assuming that we could get all the actors back together, I think this is something we would do possibly next fall, fall 2018,” Bloys told Deadline at the January TCA. Talks with the cast are currently underway, focusing on their availability. Milch has penned a script for the film.

Olyphant currently stars opposite Drew Barrymore in Netflix’s Santa Clarita Diet, which launches its second season on Friday.
